Describes the expansion of the Thomson scattering system of the DIII-D tokamak for the identification and reduction of stray light sources. Initial system design; System alignment use of charge-coupled device camera; Baffle modifications; Sources of stray light.

Describes a Thomson scattering diagnostic planned for the W7-X stellarator that provides sufficient access to the vacuum vessel to probe several scattering geometries, allowing for scattering vectors parallel, perpendicular, and oblique with respect to the magnetic field. Experiences from the...

The neutral particle analyzer with energy and mass selection capability built for JET is described. The analyzer is able to detect in the same shot both H atoms from 0.3 to 320 keV and D atoms from 0.15 to 160 keV. In order to optimize the ion optics of the analyzer an oblique entrance in the...

Beam steering technique using aperture displacement was applied to produce uniform beam distributions for testing high heat flux components. Only the apertures of a suppression grid of the JT-60 ion source were programmatically displaced with respect to those of the other three grids. Flat heat...

Reports on the first results of Thomson scattering-based fast ion and alpha-particle diagnostics at JET Joint Undertaking in Great Britain. Description of the diagnostic system; Initial operation; Ongoing developments for alpha particle measurements.

Details the commissioning of the divertor Thomson scattering (DTS) system for the DIII-D tokamak. Achievement of two-dimensional mapping of the divertor region; Measurement of the scattered and plasma background light; Schematic layout of the DTS diagnostic.

Presents an abstract of a paper reporting on Thomson scattering measurements in the divertor region of a tokamak. Use of the data as input to boundary physics codes such as UEDGE and DEGAS and to benchmark the predictive capabilities of the codes; Characterization of tokamak disruptions; Fiber...

Focuses on error analysis of Thomson scattering data at the Rijnhuizen tokamak project in the Netherlands. Overview of the Thomson scattering diagnostic; Error determination; Instrument profile; Convolution of the fit function.
